SPECIFICATION forming part of Letters Patent No. 603,354, dated May 3,1898.

Application filed June 1, 1897. Serial No. 638,989. (No model.)

To all whom it may concern.-

Be it known that I, BENJAMIN F. WILLIS- TON, a citizen of the UnitedStates, residing at J ackson,in the county of Jackson and State ofMichigan, have invented certain new and useful Improvements inFoundation Piers, of which the following is a specification, referencebeing had therein to the accompanying drawings.

My invention is primarily designed to furnish a convenient, cheap, andlasting foundation-pier for the support of pipe-lines and otherstructures which are supported upon posts or piers in the ground; and myinvention consists in the peculiar construction of a concrete pier andin its combination with a cap, all as more fully hereinafter set forth,and shown in the accompanying drawings, in which Figure 1 is a detachedperspective view of the concrete block forming the ground portion of thepier. Fig. 2 is a similar perspec- Fig. 3 is a vertical cross-section ofFig. 2 in the plane of the bolts.

A is a solid block of concrete forming the pier proper. In generaloutline this block represents a'parallelepipedon provided upon twoopposite sides with sunk panels 6 and upon the other of its two sideswith the vertical bolt recesses 0, adapted to receive the shank and headof the bolts 0. The whole pier is thus integrally formed by casting the7 material in its plastic condition in a suitable form and allowing ittoharden as in the wellknown manner. I

B is the cap, preferably consisting of a solid block of wood and of asize to project with its ends beyond the sides of the pier which havethe bolt-recesses, while the sides are flush with the paneled sides ofthe pier.

G are headed bolts uniting the cap to the top of the pier. The shanksand heads of In practice, the device being constructed and arranged asshown and described, it will be seen that it forms a Very convenientmeans of forming a permanent foundationas, for instance, in theconstruction of pipe-lines and like conduit-s, where such piers are usedat intervals to support the pipe-carriers. The pier being planted in theground at a depth to support the cap upon the ground, it is held veryfirmly in line. The sunk panels also form means to the same end.

My improved foundation-pier is adapted for extended use in building allmanners of foundations in which the superstructure has to be firmlysupported and anchored in the ground, and it permits of either renewingthe caps or bolts, or both, if decay or rust has rendered them insecurewithout disturbing the foundation proper.

What I claim as my invention is 1. The combination ofa pier formed withrecesses in opposite sides thereof, the cap extending over the sidescontaining such recesses and the bolts located in said recessesdetachably securing it to the pier.

2.. The combination of the concrete pier a provided with sunk panels 6and recesses c upon opposite sides respectively, the wooden cap Bextending over the sides containing the recesses and the headed bolts 0detachably engaging into the recesses c and uniting the pier and capdetachably together.

In testimony whereof I affix my signature in the presence of twowitnesses.

BENJAMIN F. WILLISTON.
